Definitions

  • the present invention relates to a device for counting and detecting flat products in accordance with the preamble of claim 1 , and to a method for counting and detecting flat products as claimed in claim 9 .
  • Devices for counting flat products are generally known technical aids for determining the number of flat products. Appropriate error correction processes can be triggered given the establishment of a deviation between an expected number of flat products and the number determined by the counting device.
  • Optical sensors are often used in counting devices in order to detect the number of flat products without contact and quickly.
  • Counting devices are disclosed, for example, in EP-A-1 661 833 and WO 2007/012206.
  • flat products transported in clamps are provided with identification information which is subjected to optoelectronic monitoring during the movement of the flat product past a monitoring point.
  • images of the identification information are recorded by means of an image recording unit.
  • the recorded images are processed electronically and control signals for downstream processing devices are generated as a result of this processing.
  • the flat products must additionally be provided with identification information that is then to be detected in an image recording process often dependent on the ambient illumination. It is impossible in this way, or possible only with relatively large outlay, to count products bearing completely against one another in a flat fashion.
  • the inventive device for counting and detecting flat products, in particular printed products has a light source, an optical sensor and an evaluation unit connected to the optical sensor.
  • the light source a laser in a preferred embodiment, has a beam shaping optics, for example in the form of optical lenses, in particular of cylindrical lenses, of diaphragms or diffractive optical elements by means of which a predetermined illumination beam profile is “impressed” on the emitted light. Objects located inside the illumination beam profile are irradiated with light.
  • the light source can be assigned an optical axis that extends rectilinearly in space starting from the light source. In the meaning of this application, this optical axis simultaneously forms a central beam axis of the illumination beam profile and is also denoted below as illumination beam axis.
  • the optical sensor for example in a preferred embodiment an electronic camera with a plurality of photosensitive elements, is equipped with a detection optics for forming a detection beam profile.
  • a camera objective for example, is used as detection optics.
  • the detection beam profile comprises all the locations from which the optical sensor can detect light.
  • the detection beam profile of the optical sensor is composed of the individual detection beam profiles assigned to each individual photosensitive element.
  • the detection beam profile of the optical sensor could, for example, be rendered visible by replacing the photosensitive elements by small light sources.
  • the illumination beam profile and the detection beam profile are aligned angularly offset from one another in such a way that they overlap in a detection region.
  • the illumination beam axis and the detection beam axis even lie in a plane.
  • this section is at least partially delimited by the illumination beam profile and can be detected by means of the optical sensor.
  • the optical sensor can generate a detection signal with information relating to the detected section of the surface profile.
  • the detection signal is passed on to a downstream evaluation unit.
  • the evaluation unit preferably a computer, can determine from the detection signal the number of the flat products that were located in the detection region at the instant of the detection.
  • the device for counting and detecting flat products is assigned a transport device.
  • the flat products moved through the detection region along a transport direction with the aid of the transport device are preferably counted continuously in order, for example, to monitor their completeness.
  • the illumination beam axis is preferably aligned in a fashion inclined to the surface normal of the, for example, flat products resting on a conveyor belt or transported by means of clamps or grippers.
  • the illumination beam profile in the detection region is preferably formed as a substantially rectilinear region, in particular as a so-called illumination line, which illuminates the section of the surface profile of the flat products in a defined way.
  • the illumination line preferably extends in a fashion substantially parallel to the transport direction.
  • a camera serving as optical sensor.
  • the detection beam profile is formed by the detection optics in such a way that an image of the illumination line projected by the light source onto the surface of the flat products is produced on the photosensitive elements of the camera.
  • an image, recorded by the camera, of the illumination line projected onto this uneven “projection surface” will reproduce the curves and offsets thereof.
  • This image information is passed on in the detection signal to an electrically connected computer.
  • An image processing program that can be executed on the computer can then determine the number of the flat products that were located in the detection region from the image of the projected illumination line with the aid of the curve and offsets.
  • the recording and/or detection time is short by comparison with the time within which a flat product has moved by the amount of its thickness.
  • the number of the flat products located in the detection region is determined solely from the detected surface profile of the flat products. It is not necessary to apply identification information to the flat products.
  • An adequate contrast in image recordings results from the fact that the light in the illumination beam profile, particularly inside the illumination line in the detection region, has been produced with a comparatively high intensity by the light source as compared with the ambient light, and so a reliable identification of the irradiated surface profile is ensured.
  • the optical sensor can, moreover, be equipped with appropriate filter elements in order additionally to reduce the interference from ambient light.
  • FIG. 1 shows a perspective illustration of a preferred embodiment of the inventive device for counting and detecting flat products having an assigned transport device transporting the flat products by means of clamps, a laser light source arranged to the side of the flat products projecting an illumination line onto the surface of the flat products transported through a detection region, and a camera located above the flat products detecting the surface profile illuminated thereby;
  • FIG. 2 shows a side view of a section of a further design of an assigned transport device, in the case of which in each case two flat products are transported, held in each case by a gripper, along a transport direction, and a further sensor of the device for counting and detecting flat products detects the grippers moved past in order to be able to assign a previously determined number of flat products to a specific gripper by means of a trigger signal generated by the further sensor;
  • FIG. 3 shows a perspective illustration of a section of the device shown in FIG. 1 , the transported flat products now being transported through the detection region in an imbricated arrangement in a fashion resting on a conveyor belt;
  • FIG. 4 shows a side view of a section of a further embodiment of an assigned transport device with flat products held on grippers individually or in pairwise fashion;
  • FIGS. 5 a - 5 e show abstracted image recordings of flat products transported through the detection region in a fashion suspended on grippers, surface profiles irradiated by the illumination line respectively being drawn by dashes, and the respectively schematic side views of the flat products being illustrated as well, purely by way of alternative.

  • the illumination beam profile 24 preferably has a higher light intensity than the ambient light, at least in a detection region defined below.
  • the light source 16 provides preferably substantially monochromatic light such as is produced, for example, by lasers, monochromatic LEDs or classic light sources equipped with a filter. It is possible in this way for the light produced by the light source 16 , scattered on the flat products 14 and detected by the optical sensor 18 to be distinguished from ambient light on the basis both of its intensity and of its spectral region, and thus to ensure a reliable detection and counting of the flat products 14 .

  • the optical axis of the optical sensor 18 is denoted below as detection beam axis 32 .
  • the optical sensor 18 is arranged above the flat products 14 such that an image of the illumination line projected onto the flat products 14 is produced by means of the detection optics 28 on the photosensitive elements of the optical sensor 18 .
